analog pressure gauge / diaphragm / process / for vacuum
process, for vacuum, for water
stainless steel, low-pressure, threaded
Min.: 0 psi
Max.: 10 psi
The Low Pressure Gauges of the SOLFRUNT® 1929 series are available in spans from 30" H2O to 10 psi and can measure pressures as low as few inches of water, due to a unique sensing element. This element is composed of several stacked diaphragm capsules with two plates contoured into a convex/concave configuration, enabling the low internal volume element to create forces needed to drive the system in very low pressure ranges.
Additionally, the sensing element can be filled and used in conjunction with Type L Mansfield & Green diaphragm seal in order to measure corrosive or viscous fluids. The 1929 model is also fully compatible with ST type diaphragm seals. All calibration settings such as scale shape and linearity can be easily adjusted from the back of the case without opening, while the pointer is adjusted by removing the front ring and window.
